Notes
[1]. In Normal mode, the functions of 8 pins are not printed, because they are flexibly configurable by the user using the
RFPDK. See Chapter 2.5 to learn how to evaluate the Normal Button Mode.
[2]. In Matrix mode, the selected pins are fixed from K1 to K5. The maximum number of buttons allowed to press at the same
time is two.
[3]. In Toggle mode, K1 and K2 are assigned as on/off buttons. K3-K6 are assigned to control the 4 data bits of the
transmitted packet.
[4]. In PWM mode, K1 and K2 are assigned as on/off buttons. K4 and K5 are assigned as increase and decrease buttons.
[5]. In Toggle and PWM modes, if
On/Off Button(s)
on the RFPDK are set to Single, only K1 is used as on and off button, if
On/Off Button(s)
is set to Separated. K1 is used as on button and K2 is used as off button.

CMT2150A-EM
Table 11. CMT2150A-EM EM-Connector Pin Definition
The module can be used in the following schemes
1.
Work with the CMT2250A-EM to demonstrate the Normal, Toggle and Matrix button modes and periodic transmission.
2.
Work with the CMT2251A-EM to demonstrate the PWM button mode.
The evaluation module contained in this Development Kits is designed with the matching network at 433.92 MHz. For
application with different frequencies, the matching network might need to be changed.
See
“
Chapter 10 Appendix: CMT2150A-EM and CMT2250(1)A-EM Schematics”
for the CMT2150A-EM Schematic.
